This chapter describes the hardware design guide on interfacing an MCU with Tuya’s modules (such as Wi-Fi, Bluetooth Low Energy, Zigbee, NB-IoT, Wi-Fi and Bluetooth Low Energy combo, and LTE).


If you plan to interface the MCU with Tuya’s module to implement connectivity to the Tuya IoT Development Platform, the hardware design guide helps you implement the UART communication.

  • Typical UART communication design between MCU and module.
  • Adapt modules to MCUs, including circuit design and software configuration.
  • Configure signal level, baud rate, and protocol for UART communication.
  • Manage power and signal processing to ensure stable communication.
  • Optimal circuit layout and impedance matching to reduce electromagnetic interference and noise.
